2 Claims. This invention relates to a waiiie steak machine and has for an object'to provide apparatus and a processfortenderingsteaks without puncturing the steak. I

I A further object is to provide apparatus including an upper member having pyramid shaped recesses to receive pyramid shapedprojections ona lower member, the projections on the lower member being staggered so that the base edges of the complemental pyramid shaped recesses of the upper member form square cutting edges to sever the muscular fibers on the top face of the steak when the steak is pushed up' into the recesses by the projections which do not puncture the steak during the deforming of the steakinto the companion recesses.

in the various views, l designates a lowermember, preferably formed of metal, halving pyramid shaped projections ll arranged in staggered relation on its upper face, see Figure 2. l2 designates an upper member, preferably formed of metal, having pyramid shaped recesses l3 formed on its lowerface, see Figure 1. The recesses receive the projections Il of the lower member [0.

' The bottom edges of all of the recesses are in a A further object is to provide a steak tendering process in connectionwith the apparatus including a step of freezing the steak solid preparatory to the processing of the steak between the members of the machine. I j I A further object is to provide apparatus of this character which will-be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order. p

With the above and other objects in view, the

common plane and the bottom edges of a single recess form a square, as indicated by heavy lines at in Figure 1.

When a steak I5 is disposed between both members and the members moved toward each other, the projections II will deform the steak into the companion recesses i 3, see Figure 3. During this deforming of the steak, the square cutting edges M will cut squares, as shown at l6, see Figure 4, in the top face of the'steak, while the projections merely push the steak into the recesses without puncturing the steak, The

, squares cut in the top face of the steak sever the invention consists of certain novel details of constructionand combinations of parts hereinafter fully described 'and claimed, it being understood that various modifications may be resorted to lwithin the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention. g

In the accompanying drawing forming a part c of this. specification:

made in the top surface of the steakby the cutting edges of the upper member.

Referring now to the drawing'in which like characters of reference designate similar parts muscular fibers of the steak longitudinally and transversely, thus rendering the steak tender.

In practice it has been found best to freeze the steak solid as a preliminary step to processing the steak in the machine, as above described. The process thus will include the steps of first freezing a steak solid; second, deforming the steak in the nature of a waffle, while simultaneously cutting squares in the top face of the steak without puncturing the steak.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

l. The process of tendering a steak consisting of freezing the steak solid; deforming the steak in the contour of a wafiie, and simultaneously with the deforming step cutting squares in the top face of the steak without puncturing-the steak.

2. The process of tendering a steak consisting of freezing the steak solid, deforming the steak in the contour of a waflle, simultaneously with the deforming step cutting squares in the top face of the steak without puncturing the steak, and maintaining the wafile appearance of the steak until cooked.
